How to close tab using close button in WPF?

Question

I am working on a WPF application where it creates a new tab when a button is clicked. It works great. I find it difficult to find how to close the button next to the tab title, like X , and close the selected tab?

MainWindow.xaml

<Grid>
        <StackPanel Name="listConnections" Grid.Column="0" Background="#4682b4" Margin="0,0,0,-0.2" >
        </StackPanel>            
        <TabControl Name="tabConnections" Grid.Column="1" TabStripPlacement="Top" Margin="0,0,0.4,-0.2">
        </TabControl>
    </Grid>
</Window>

add Tab method to create new tabs when you click MainWindow.xaml.cs

public void addTab(Connection connection)
{
    TabItem tab = new TabItem();
    tab.Header = connection.name;
    tabConnections.Items.Add(tab);
}

Is there an easy way to make a close button?

The answer to the question:

   Use the stack panel to align the text box and close the image horizontally. Check out the example below.

TabControl. . , . Tab .

// This class will be the Tab int the TabControl
public class ActionTabItem
{
    // This will be the text in the tab control
    public string Header { get; set; }
    // This will be the content of the tab control It is a UserControl whits you need to create manualy
    public UserControl Content { get; set; }
}

/// view model for the TabControl To bind on
public class ActionTabViewModal
{
    // These Are the tabs that will be bound to the TabControl 
    public ObservableCollection<ActionTabItem> Tabs { get; set; }

    public ActionTabViewModal()
    {
        Tabs = new ObservableCollection<ActionTabItem>();
    }

    public void Populate()
    {
        // Add A tab to TabControl With a specific header and Content(UserControl)
        Tabs.Add(new ActionTabItem { Header = "UserControl 1", Content = new TestUserControl() });
        // Add A tab to TabControl With a specific header and Content(UserControl)
        Tabs.Add(new ActionTabItem { Header = "UserControl 2", Content = new TestUserControl() });

public partial class Window1 : Window
{
    private ActionTabViewModal vmd;

    public Window1()
    {
        InitializeComponent();
        // Initialize viewModel
        vmd  = new ActionTabViewModal();
        // Bind the xaml TabControl to view model tabs
        actionTabs.ItemsSource = vmd.Tabs;
        // Populate the view model tabs
        vmd.Populate();
    }

    private void Image_MouseDown(object sender, MouseButtonEventArgs e)
    { 
        // This event will be thrown when on a close image clicked
        vmd.Tabs.RemoveAt(actionTabs.SelectedIndex);
    }
}
